Some 6.5 million people in South Sudan - more than half of the population - could be in acute food insecurity at the height of this hunger season (May-July), three United Nations agencies warned. The situation is particularly worrying in the areas hardest hit by the 2019 floods, where food security has deteriorated significantly since last June according to the Integrated Food Security Phase Classification (IPC) report released by the Government of South Sudan, the Food and Agriculture Organization of the United Nations (FAO), the United Nations Children's Fund (UNICEF) and the World Food Programme (WFP). Particularly at risk are 20,000 people who from February through April will be suffering from the most extreme levels of hunger ("catastrophe" level of food insecurity or IPC 5) in Akobo, Duk and Ayod counties that were hit by heavy rains last year, and need urgent and sustained humanitarian support.
